?? original poster has what appears to be about 90 - 100 watts load. Seems like 1000 watt inverter is way overkill. Harbor Fright has 400 watt inverters for $30 less weekly 20% off coupons. buy two so you have a spare. my first one has been to two burns, and still works, the spare is still unwrapped.

Also seems like a lot of stuff to go from the honda generator internal DC generator and inverter to 120 ac, then a battery charger, battery, inverter, to power dc lights and stereo.

imho

We opted for a 2000 watt Honda EU instead. Read my signature! No..at $600 we couldn't pass it up. Especially, since you can splice two EU generators together...for the hot tub...next year.

You can do your own searching, but get at least a 1000W (continuous) inverter if you can but make sure to look at the continuous and peak ratings together. The one below is 1000W continuous/2000W peak.

You're getting the gist of this, right? Run your things off of the battery/inverter. When the battery gets low, charge it with the generator.

At that price, why not... it should handle what you've described. Hell I have an 800-watt and a 1200-watt inverter on my MV already but I might grab a couple of those little things myself and split the load between them just so I have disposable units that I can subject to the corrosive playa and not cry when they die.

You just need wire, big fat wire. The smaller the gauge number, the bigger the wire is. 10 gauge will probably be fine for what you're doing. If you figure on using it at full capacity ever, go with 8 gauge wire. The inverter has terminals on it that you can put the wire ends (with just enough insulation stripped off to allow contact but not so much that you have excess bare wire hanging out) into and screw them down tight. At the battery, if you get a deep-cycle style battery or so-called "marine" battery it will have threaded posts on it. The threaded posts will have wing nuts on them. the best thing is to put some ring terminals on the wire ends. You can get them at an auto parts store or maybe even Home Depot.If you just get a regular car battery, you can put regular battery-post clamps on it, and use the bolts on them to attach your inverter wires.

It should come with attachment wires. The picture most likely doesn't show them just to keep it clean looking. Get the unit first and see what it comes with.

Yeah.. because uh.. all the hundreds of thousands of people that are/have been using them for years now must be doing it wrong..

tattoogoddess wrote:No the geni to the volt monitor thing (that damn contraption used when charging the battery. ) lol

There's no "volt monitor" that I'm aware of. You would be talking about the battery charger.. which has a built in volt monitor and will shut off when the battery is fully charged.

Side note: Don't skimp on the rating of the battery charger since you'll want to get it done as quickly as possible and shut the genny off to save fuel. That digital 100A unit that I linked is your best bet for the $$ from what I've seen..

Thanks for bringing up your original question, and thanks for asking your followup questions. You're probably like the vast majority of people, very few anymore have the knowledge about electrical stuff like this, so you have absolutely nothing to be hesitant about, you're similar to the majority nowadays. Most people follow the maxim, "Better to keep quiet and leave people unsure about whether you know anything about a subject, rather than speak and remove all doubt." But, you have questions, and ask them. Thank you for doing this!

It's good feedback to ones that are familiar with electrical stuff to know how much of what is communicated is actually understood by the recipient. And, it's good feedback for understanding why most BRC theme camps are so dark and so quiet unless a generator is actually running. Only a small percentage of people understand how simple it is to hook up a battery to an inverter to a stereo and LED lights, yet most of the respondents on threads such as this one just erroneously assume that it's basic knowledge.

Another good feedback from your thread is why people go out and get a generator for the playa, when what they want to do could easily be done with a battery/inverter, and just figuring out how to recharge the battery once or twice during the week. It's that people just automatically think "generator" for power, and are focused on getting a generator, without realizing that there are cheaper ways of doing so and that the other methods may provide a better solution (longer hours of use, and quieter).

The simplest way of hooking an inverter to a car-style battery is alligator clips.

Just make sure you have really heavy gauge wire (as others have said, the lower the gauge # the thicker the wire). Something in 10 or 8 gauge is good. (check the inverter and see how many amps it draws from the 12V feed and ensure that everything going to the battery is at least that amp rating! If it has a higher amp rating, that is fine [better to have more current capability than less]).

If you can, have the power cables from the inverter directly connected to the battery. A lighter plug will possibly reduce the available current and could give you grief (not always, but if it is rated for less amperage it might cause "inverter squeeling", aka not enough power for what you are using).

YMMV

ok so i need help again. the two red balls are the disco balls i was talking about.the yellow are extension cords( roughly 15 foot one) x 2the purple thing is a power stripthe red lines are Christmas lights. (led) 30-40 feetthe blue thing is the battery and the 400 watt inverter

one- what gauge? is 14 ok?two- does it matter what power strip I use?three with all of this plugged in will I be ok?

Everything you described is somewhere around 200 watts of power all told. At 120V, that's around 2 amps. If you put both extension cords in line, 30' and calculated the total resistance up-and-back (60 feet), 14 gauge cable would be about 0.18 ohms. At 2 amps, that's 0.36 volts lost in the wire, so if you put exactly 120 volts in, you'd get 119.64 volts out. If you went with even cheaper 16-gauge, the resistance would be about 0.28 volts, and you'd lose 0.56 volts in the wire.

So yeah, 14 gauge is plenty.

And likewise, the amount of power would be no trouble for even the cheapest power strips.

Of course, I still stand by my complaint of modified-sine inverters, I'm sure the disco ball motors will run hot, and I bet at least one of them will fail if you try and run it all night. ... we shall see.

Ok so realize I never reported back. That Schumacher thing. Fucking sucked!!! It dies the first day. We took it apart and everything. Never wanted to turn back on. Had it set right and everything. It charges it a bit then just stopped at the last 20%. Something we did wrong? Next year looks like it will be strictly genis

I have that same charger. Never had a problem, even charging four 110 AH deep cycle batts in parallel. But they are picky when you try to charge small batteries or batteries with a weak or low cell.

Something else: that charger will continue to charge even after it says "done" if the battery needs it. So keeping it connected isnt a bad idea. As long as it isnt flashing all 888, its still working and doing its job.

Regardless, the geni is the way to go. The honda also has an 8-amp 12v unregulated charger built in.

as mentioned earlier, 14 or 16 ga is ok for 120v wiring. 400watt inverter will only put out at most 6 -8 amps before shut down. Battery to inverter needs to be BIG WIRE 8 or 6 ga.

These were brand new batteries. Only used once for 6-8 hours with the inverter I was told to get here. The battery dropped below 12v so we charged. Said 20% left to charge then stayed there. The thing got hot and we un plugged it. Never turned back on.
